Saga +20 wet macro lens question.

Hi buddies, I have been using different wet macro lenses with a Sony Rx100 VA along the years, such as Fit pro +5, Saga+10, Subsee +10, and Fit pro +13 without problems and getting quality from all of them. I never had all of them at the same time to stack up and get any close to +20 so I couldn't try myself. The thing is I have just found a pretty bargain for the Saga +20 and I wonder if the focus is too challenging due to its massive magnification before making my mind to buy it... Or if there are any other things to consider with such a big macro lens...

Any advices of any +20 wet macro lenses user here are welcome. Thanks in advance!! 😉😎
